引入gin
go get -u -v github.com/gin-gonic/gin
Restful風格示例
package main
import (
"github.com/gin-gonic/gin"
)
func getBook(c *gin.Context){
c.JSON(200, gin.H{
"message":"get book",
})
}
func createBook(c *gin.Context){
c.JSON(200, gin.H{
"message": "create book",
})
}
func updateBook(c *gin.Context){
c.JSON(200, gin.H{
"message":"update book",
})
}
func deleteBook(c *gin.Context){
c.JSON(200, gin.H{
"message":"delete book",
})
}
func main() {
r:=gin.Default()// 使用默認engine
r.GET("/book", getBook)// 配置路由
r.POST("/book", createBook)
r.PUT("/book", updateBook)
r.DELETE("/book", deleteBook)
r.Run(":9090")
}
使用postman測試一下
vscode里面有個vsc-postman插件，很好用。
